CATARACTS & CATARACT SURGERY
What is a Cataract?
Inside of our eyes is a natural lens that is clear. When this lens becomes cloudy it is called a cataract.
Aging is the most common cause of cataracts because of natural changes that occur in the lens as we get older.
Cataracts may also develop in certain medical problems like diabetes or in the case of eye injuries or prior eye surgery.
NORMAL = CLEAR LENS
CATARACT = CLOUDY LENS
What is cataract surgery?
You don’t necessarily need surgery as soon as a cataract is directed. Cataracts can interfere with your vision, but they don’t damage your eyes. Cataract surgery is performed when a patient’s cataract develops to the point where it interferes with his/her activities of daily living.
Cataract surgery is quick, safe, and effective - it involves removing the cataract and replacing it with an artificial lens, called an intraocular lens (IOL). Dr. Gupta offers the latest in cataract surgery technology as well as a full selection of IOLs, including models that can treat astigmatism and reduce or eliminate your need for glasses or contacts.
Typically, wait times for surgery with Dr. Gupta are less than four weeks. If you have cataracts in both eyes, you may not need surgery on both cataracts at the same time.
- Blurry vision
- Glare or sensitivity to light
- Difficulty with vision at night or feeling like you need more light to read.
Initially these symptoms may be treated with glasses but for the majority of patients, symptoms progress to the point where cataract surgery becomes an option.
The determination of when a cataract is "ripe" is highly personalized and takes into account your daily activities (for example: driving, golfing, tennis, clear near work like sewing or reading). In other words, if you feel like you cannot see well enough to live your life, the cataract may be ripe.
A comprehensive/dilated exam is important at this point to make sure that the cataract has indeed grown and that there isn't another cause for the vision changes (like glaucoma or macular degeneration).
What is laser cataract surgery?
Laser cataract surgery uses precision-guided technology during cataract surgery. The result is a more precise procedure that may result in better vision as compared to traditional/manual cataract surgery.
Do I have to have an artificial lens?
Yes. During cataract surgery, Dr. Gupta removes the natural lens of the eye because it turned cloudy and became a cataract. In order to improve your vision, she will insert an artificial lens, called an intraocular lens (IOL), at the time of surgery. Without an IOL your vision will be extremely blurry and you will need very strong "coke-bottle" glasses to improve your vision.
IOLs are safe, reliable, and excellent in restoring vision. They are made of a flexible, acrylic material that will not deteriorate over time. Since they are plastic you do NOT have to worry about them when going through a metal detector or any other security screening device.
Are there different types of IOLs?
There are three main types of IOLs, each with their own indications, benefits, and uses.
1. Standard Lens
2. Toric Lens
3. Multifocal Lens
